7:40 is time when usually “5ubuntu3: restart” is written in syslog.
and there were SystemToolsBackends.pl running (i even has not known about that script). and there is a strange file that may be not related to this: /sqlvee4zj .
also there is something that gives some suspicion in chat log.
and my password has been changed.
15:28 gmt +3 : i have written about my suspicion in several channels were person about whom i thought that he can be “cracker” or “hacker” and linked to this blog post in the irc network were i am connected much time and have seen that in log in little #test channel where i was connected. then i have been more really attacked today through xchat >2009-12-17 9:36 but i see now that that was not only for me, for all or many chat users<. and i am sorry! i think now may be i have forgotten my password myself!!! because i have changed it just yesterday. i tried several variation today but now i have remembered one thing about the password, it is a pity, i cannot check that now, because i have changed it.
